I like "You're A Big Boy Now" and "I Want to Know" from BIG. Also, "Let Me Entertain You" from GYPSY and "When I Get My Name in Lights" from the BFO. "Consider Yourself" from OLIVER, when the Dodger is played by a child and not a 17 year old teen.
And if she'll say, "My darling, I'm yours!" I'll throw away my striped tie and my best pressed tweed, all I really need is the girl...
